OBJECTIVEThis study aimed to evaluate whether Hwangryunhaedoktang (HHT), a herbal compound, has an inhibitory effect on lipopolysaccharide (LPS)-induced inflammation in RAW264.7 macrophages.
METHODSThe effects of HHT were evaluated by confirming nitric oxide (NO) production and expression of inducible NO synthase (iNOS) and mitogen-activated protein kinases (MAPKs) in LPS-stimulated RAW264.7 macrophages via the Griess assay, Western blotting, and real-time reverse transcription quantitative polymerase chain reaction. Western blot analyses and luciferase assays were used to evaluate whether HHT has an effect on the phosphorylation and translocation of nuclear factor-κB (NF-κB). The secretion and expression of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined via enzyme-linked immunosorbent assay and Western blot analyses.
RESULTSHHT suppressed LPS-induced NO production and expression of iNOS in a dose-dependent manner. Additionally, MAPKs activation was also attenuated via inhibition of phosphorylation of extracellular signal-regulated kinases 1/2, c-Jun N-terminal kinase and p38 which were related to inflammatory pathway. Furthermore, HHT also effectively attenuated NF-κB activation and its translocation to the nucleus, a process that is closely linked to inflammation. LPS normally induced the expression of inflammatory cytokines such as TNF-α and IL-6, but the secretion and expression of TNF-α and IL-6 were significantly attenuated by pretreating the cells with HHT.
CONCLUSIONHHT suppressed LPS-induced NO production by blocking the activation of NF-κB and MAPK signaling pathways in RAW264.7 macrophages. Furthermore, HHT may have an anti-inflammatory effect by suppressing the LPS-induced secretion of TNF-α and IL-6. Therefore, the traditional herbal formula HHT might be a useful potential therapeutic agent for inflammation.

PURPOSE: This study evaluated powdered burn wound dressing materials from wild silkworm fibroin in an animal model. METHODS: Fifteen rats were used in this experiment. Full-thickness 2x2 cm burn wounds were created on the back of rats under anesthesia. In the two experimental groups, the wounds were treated with two different dressing materials made from silkworm fibroin. In the Control Group, natural healing without any dressing material was set as control. The wound surface area was measured at five days, seven days and 14 days. Wound healing was evaluated by histologic analysis. RESULTS: By gross observation, there were no infections or severe inflammations through 14 days post-injury. The differences among groups were statistically significant at seven days and 14 days, postoperatively (P<0.037 and 0.001, respectively). By post hoc test, the defect size was significantly smaller in experimental Group 1 compared with the Control Group and experimental Group 2 at seven days postoperatively (P=0.022 and 0.029, respectively). The difference between Group 1 and Group 2 was statistically significant at 14 days postoperatively (P<0.001). Group 1 and control also differed significantly (P=0.002). Group 1 showed a smaller residual scar than the Control Group and Group 2 at 14 days post-injury. Histologic analysis showed more re-epithelization in Groups 1 and 2 than in the Control Groups. CONCLUSION: Burn wound healing was accelerated with silk fibroin spun by wild silkworm Antheraea pernyi. There was no atypical inflammation with silk dressing materials. In conclusion, silk dressing materials can be used for treatment of burn wound.

Biliary cast describes the presence of casts within the biliary tree. It is resultant sequel of cholangitis and hepatocyte damage secondary to bile stasis and bile duct injury. Biliary cast syndrome was first reported in patient undergone liver transplantation. The pathogenesis of biliary cast is not clearly identified, but proposed etiologic factors include post-transplant bile duct damage, ischemia, biliary infection, or post-operative biliary drainage tube. Although biliary casts are uncommon, most of biliary cast syndrome are reported in the liver transplant or hepatic surgery patients. A few reports have been published about non-transplant or non-liver surgery biliary cast. We report two cases of biliary cast syndrome in non-liver surgery patients.

BACKGROUND: Myoclonic movement is a common problem during induction of anesthesia with etomidate. We investigated the influences of pretreatment with remifentanil on etomidate induced myoclonus. METHODS: Ninety ASA class I patients were divided randomly into three groups. Group NS received normal saline 2 ml as placebo (n = 30), group R0.5 and group R1.0 were pretreated with remifentanil 0.5 microgram/kg (n = 30) or 1.0 microgram/kg (n = 30) 1 minute before induction with etomidate 0.3 mg/kg. Orotracheal intubation was performed after administration of rocuronium 0.5 mg/kg. We assessed the incidence, onset, duration and intensity of myoclonus. Mean arterial pressure (MAP), heart rate (HR) and bispectral index (BIS) were recorded during induction. RESULTS: Twenty five patients developed myoclonus in group NS (83.3%), 3 patients in group R0.5 developed myoclonus (10%), as did 5 patients in group R1.0 (16.7%). Moderate to severe myoclonus of grade 3 and 4 were found 66.7% of patients in group NS, whereas no patients in both remifentanil pretreated groups developed this grade of myoclonus. The duration of myoclonus was reduced significantly in the remifentanil groups: 93.8 +/- 59.5 sec in group NS, 49.3 +/- 34.9 sec in group R0.5, 36.0 +/- 27.0 sec in group R1.0 (P < 0.05). HR was decreased by pretreatment with remifentanil prior to induction, while MAP and HR were decreased after induction with etomidate (P < 0.05). BIS changes were not different among the three groups. The dose dependent differences between the two remifentanil doses were not noticed. CONCLUSIONS: Pretreatment with remifentanil significantly reduced the incidence, duration and intensity of etomidate induced myoclonus.

PURPOSE: Multidrug-resistant tuberculosis (MDR-TB) is an emerging threat to human beings. However, there is little data on the current status of MDR-TB in Korea. This study investigated the current status of MDR-TB in Korea using a survey of all the data from drug susceptibility tests (DST) performed across the country over the last three years. METHOD: The DST results between Jan. 2000 and Dec. 2002 from 7 laboratories, which were in charge of all antituberculous DSTs across the country as of March 2002, were collected and analyzed to determine the actual number of drug-resistant or MDR-TB patients, annual trend, degree and pattern of resistance against anti-TB drugs, etc. RESULTS: Six laboratories used the absolute concentration method for DST and one used the proportional method. 59, 940 tests had been performed over the 3 year study period. The number of DST performed annually was 18,071, 19,950, and 21,919 in 2000-2002, respectively. The number of resistant tuberculosis patients (resistant against at least one anti-TB drug) had increased by 16.9% from 6,338 in 2000 to 7,409 in 2002. The rate of resistant tuberculosis among all DST results was 35.1% in 2000, 34.5% in 2001, and 33.8% in 2002. The number of MDR-TB patients (resistant against at least both isoniazid and rifampin) showed an increasing trend (14.5%) from 3,708 in 2000 to 4,245 in 2002. CONCLUSION: Approximately 4,000 MDR-TB cases are newly identified by DST annually and the number is showing an increasing trend. This study suggests that in order to cope with the current MDR-TB situation, the DST methods will need to be standardized and more aggressive measures will be required.

Laparoscopic cholecystectomy has been popularized all over the world as the treatment of choice for unnecessory symptomatic or asymptomatic gall stones. Initially, this surgery was applied to limited indications, but nowadays the indications of the surgery have been expanded to include severe, inflamed, complicated patients with gall stones, which used to be thought of as contraindications in the past. Surgeon,s technical improvement and newly devised surgical instruments made it possible to expand the limit of surgical indications for laparoscopic cholecystectomy. However, anatomical disorientation due to severe inflammed gall bladder is still the drawback to the possible occurrence of laparoscopic bile duct injury and bleeding. We have a clinical analysis of 32 cases of laparoscopic cholecystectomy for acute cholecystitis or G.B.empyema, surgical time,safety and case were evaluated. Two patients were converted to open laparotomy because of intraoperative bile duct injury and anatomical disorientation by hepatic flexure colonic interposition. As a result, we suggest that even in patients with subphrenic abscess or bile peritonitis secondary to G.B.empyema could be the indications for the laparoscopic cholecystectomy if surgeon's ability or patient's condition allow it.

The classic clinical manifestations of acute suppurative cholangitis were first described by Charcot in 1877 as a triad of fever(and chill),jaundice and right upper quadrant pain. In 1959,Reynolds and Dargan characterized acute suppurative cholangitis as a distinct clinical entity manifested by a clinical pentad of Charcot,s three signs plus shock and central nervous system depression.We have clinical analysis of acute suppurative cholangitis,218 cases who were admitted in Chonnam Hospital from Jan.1989 to Dec.1995.All cases were treated conservatively initially,and then delayed operation was performed when the patients were improved from the septic condition by cholangitis.
